Hello Leo, I have to agree that the apistos. that I have dealt with get leery over a really light substrate. If you are trying to breed your guys I would eliminate this variable and go with a dark substrate. On a different note, light coloured substrates tend to wash out the colour of many fish. Given the way any given cichlid's colour changes according to mood, health, substrate, etc. I would avoid light coloured substrates if only for the aesthetics.
